Any chance you stripped the threads in the heater block and it yeeted the nozzle out?
Seems like a stretch, but the only explanation that comes to mind.

Especially if you attempted the nozzle change while cold. PLA is a hellacious thread locker. It WILL strip aluminum threads.
OP could compare a thread gauge to the female/internal threads on the block to find out. Or, more simply, do two things.
If #1 pulls out a new nozzle... Yeah... replace or rethread (good luck) the block.
If #1 sticks strong but #2 pulls out, replace the nozzle and hope it was just a shitty, undersized, nozzle. I don't expect this to be the case, but eliminate all simple problems before trying to remedy a (maybe non-existent) larger problem. Troubleshooting 101
I changed the nozzle while the heat block was 200C.
I was afraid of this but turns out threads are still there. As I explained in a previous comment I successfully printed with another 0.8 nozzle.
Am I understanding that you found the nozzle IN the print itself? Like it unthreaded and left the heat block?
Have you tried threading another nozzle into the heat block just to see if there are still threads left?
Yes exactly this is.
After this I used a 0.8 nozzle. And could print with it. So threads are still there.
I suppose I mistakenly didn't fully screwed the 1.0 nozzle. With the large layer width Pla stuck on the nozzle, as the print was a rectangular shape on each turn that pla applied some tork and nozzle unscrewed.
